1uF or larger capacitor directly across the load to reduce excessive ripple. For sensitive applications with high-speed acquisition at the load, high frequency noise may be reduced significantly by placing a 0.1uF capacitor directly across the load, as close to the load as possible.

Page 10: Power Connections
This transmitter is powered from 12–32VDC (36VDC peak) by connecting power as shown below. This transmitter can be optionally powered (or redundantly powered) via the DIN rail bus when coupled to the DIN rail bus connector (Acromag Model 1005-063) and a bus terminal block (Acromag 1005-220 or 1005-221). This optional method can allow several modules to share a single power supply without wiring to each individually. -
Page 11: Optional Bus & Redundant Power Connections
Important – End Stops: If this module uses the optionally powered (or redundantly powered) via the DIN rail bus for hazardous location installations (Class I, Division 2 or ATEX Zone 2) it must use two end stops (Acromag 1027-222) to secure the terminal block and module (not shown). -

Page 14: Configuration Software
CONFIGURATION SOFTWARE Quick Overview – Android This transmitter can be configured and calibrated via the Acromag Agility™ Config Tool App. This software can be downloaded free of charge from the Google Play store at play.google.com. To connect to this transmitter, a USB OTG (On-The-Go) cable (Acromag 5028-565) and USB A to Mini-B cable (Acromag 4001-113) are required. -

USB connection to a PC or laptop. The configuration software can be downloaded free of charge from our web site at www.acromag.com. This software is also included on a CD-ROM bundled with the Configuration Kit TT-SIP (see Accessories). For this transmitter, use program “TT339 Config.exe”. - Page 16 Help Calibration Status (Bottom of Window) message pertaining to the item you The Calibration Status bar at the bottom of the window will display status pointed to. messages relative to calibration.

Page 17: Operation Step-By-Step
Now that you have made your connections and applied power, you can execute the “TT339 Config.exe” software to begin configuration of the transmitter (software is compatible with XP or later versions of the Windows operating system). Acromag, Inc. Tel: 248-295-0880 http://www.acromag.com... - Page 18 You will not be able to configure, calibrate, or test the transmitter without power applied. After executing the Acromag Configuration software for this transmitter, the window shown at left will appear, if you have not already connected to the transmitter via USB (note fields are blank under these conditions).

WARNING: Do not exceed 15VDC with the internal pull-up or pull- down resistors enabled, or damage to the circuit will result. Limit internal pull-up/pull-down resistor power to less than 0.25W. Disable the Pull-up/Pull-down if the input to the transmitter is AC mains voltage (120V Acromag, Inc.

Page 23: Calibration (Optional)
NOTE: To measure current, you can alternatively connect a voltmeter across a precision load resistor, and then accurately read the output current as a function of the IR voltage drop produced in the resistor (recommended for current outputs).

Its enclosure is not meant to be opened for access and can be damaged easily if snapped apart. It is highly recommended that a non-functioning transmitter be returned to Acromag for repair or replacement. Acromag has automated test equipment that thoroughly checks and calibrates the performance of each transmitter, and can restore firmware. -
