CHAPTER 1. OVERVIEW 1.0. Product Summary The CTI 2558 Eight Channel Analog Input Module is a member of Control Technology’s family of I/O modules compatible with the 505 programmable controllers. It is designed to SIMATIC® translate an analog input signal into an equivalent digital word which is then sent to the programmable controller (PLC). -

Always use this bag for protection against static damage when the module is not inserted into the I/O backplane. WARNING: Ensure that the power supply is turned OFF before connecting the wires to the I/O base. CTI 2558 Installation and Operation Guide... -
Page 27: Configuring The Module
For each input channel operating in voltage mode, set the corresponding Voltage Range Jumper to “5V” for 0 to +5V or –5 to +5V input range or “10V” for 0 to +10V or –10 to +10V input range. As shipped, the 2558 is in “5V” range. CTI 2558 Installation and Operation Guide... -

“EN” position; to disable, set to the “DIS” position. Since many analog input signals contain noise, CTI recommends using digital filtering unless maximum response time is required. As shipped, digital filtering is enabled for all 8 analog inputs. CTI 2558 Installation and Operation Guide... - Page 30 “COM” (common) position. To isolate individual channels, choose the “ISO” (isolated) position. As shipped, all 8 channels are in “COM” (common) mode. 2.3.9. Jumper Settings for Future Reference See Appendix B.

To assign an input to a specific channel, locate the appropriate channel position on the screw terminal connector as shown in the following figure: Figure 2.3 Screw Terminal Connector Wiring CTI 2558 Installation and Operation Guide... - Page 32 2.5.3. Connecting the Shield Wiring Control Technology Inc. recommends that all wires be shielded twisted pair with a foil wrap shield and a separate drain wire and that they be installed in a metallic conduit. Use Belden cable 8761 or equivalent which contains a foil wrap shield and a separate drain wire.
