CC (Contact Closure) When the input to the SRM is open there will be 24Vdc present at the input terminals. When the input to the SRM is closed there will be a maximum of 55mA flowing through the closed circuit. -
Page 8: Section 2 - Calibration Bench Check
April 2018 Section 2 - Calibration Bench Check We highly recommend that you perform a bench check of the SRM prior to installing it in the field. Doing this will ensure that it is operating within your expectations or requirements. - Page 9 User’s Manual 225-765-00G Safety Relay Module April 2018 Table 2.1. Bench Check Equipment for the SRM. Device Specifications Power Supply Calibrated, regulated 24Vdc, -5% to +10% Load Resistor 20 ohm 1/4W resistor Ohmmeter Calibrated to an accuracy of ±0.5% All referenced product names are the sole property of their respective manufacturers Figure 2.1.

Note: Make sure to bench check the instruments prior to installation. Also, install all instruments in their intended application and on their rail before making any electrical connections. Allow enough room for pivoting instruments vertically on the rail for removal in applications involving multiple banks of SRM. Terminal Designations Figure 3.1. Terminal Designations... -
Page 11: Dimensions
The SRM is housed in a DIN case that can be mounted on 35mm Top-Hat (EN50022) DIN-rail. To mount the SRM on a Top-Hat DIN-rail, seat the upper extrusion on the unit back panel over the top lip of the rail and pivot downward until the housing locks into place. -
Page 12: Electrical Connections
Equipment Ratings The SRM accepts a contact closure input and switches outputs up to 5A at up to 250 Vac or 30 Vdc for NO contacts and 1A at up to 250Vac or 30Vdc for NC contacts. It does not generate hazardous voltages but may switch hazardous voltages (>50Vac) on its output contacts. -

EMC directive. The Low Voltage Directive also applies to the SRM when connecting any of its output relay con- tacts to voltages greater than 50 vac. In order to comply with EN61010-1 (Low Voltage Directive) all guidelines in this section must be followed. -
Page 14: Section 4 - Operation And Maintenance
The Power LED will be green when appropriate power is supplied to SRM. • Input LED – When the SRM Input is open, the Input LED will be red. When the SRM Input is closed, the Input LED will turn green. -
Page 15: Maintenance
Safety Relay Module April 2018 Maintenance Moore Industries suggests a quick check for terminal tightness and general unit condition every year. Always adhere to any site requirements for programmed maintenance. Fuse Replacement Input power and all output terminals are fuse protected. If maximum voltage or currents are exceeded on the input or output terminals, one or more fuses may blow and will need to be replaced.. -
Page 16: Section 5 - Applications
This section provides some examples of typical applications for the SRM. Typical SIL 1 or SIL 2 Application The SRM used in a standard SIL 1 or SIL 2 application with up to three outputs. Figure 5.1. SRM in SIL 1 and SIL 2 applications... -
Page 17: Sil 1 Or Sil 2 Application Using Monitor Output
April 2018 SIL 1 or SIL 2 Application using Monitor Output The Monitor and Input contacts of the SRM may be connected to a PLC, DCS or other monitoring device for diagnostic purposes. Figure 5.2. SRM in SIL 1 and SIL 2 applications using Monitor output. -
Page 18: Sil 1 Or Sil 2 Application When Used With "Wet" Relay/Contact Outputs
In this instance the source relay output is used to apply power to the SRM rather than being applied to the input of the SRM. By shorting the CC input terminals of the SRM, the outputs of the SRM will be energized when the source relay output applies voltage to the SRM’s power terminals. -
Page 19: Section 6 - Srm In Safety Instrumented Systems
April 2018 Section 6 - SRM in Safety Instrumented Systems The SRM is designed for use as an element of the safety instrumented system as defined by IEC 61508-4 paragraph 3.4.1. This user manual contains all of the information needed to install, operate and maintain this product. -
Page 20: Installation
• Input LED – When the SRM Input is open, the Input LED will be red. When the SRM Input is closed, and the Input LED will turn green. -
Page 21: Proof Test Procedure
Except for the fuses, the SRM is not intended to be repaired on site and has no components needing maintenance or regular replacement. On device failure, the SRM should be returned to Moore Industries World Headquarters in North Hills, CA U.S.A. - Page 22 Bypass the safety logic solver or take other appropriate action to avoid a false trip. Disconnect all wires from SRM. Using an ohmmeter, measure the resistance between the case and all exposed pins on the front panel. Verify that the measured resistance is greater than 1M Note: this test for shorts between the power or ground to the case.
