Reliance 57652 0-57652-D controller module

Position Demand Input 

Connect a shielded twisted-pair cable from the system controller (4 to 20) mA output to DEMAND IN+(37) and DEMAND IN–(38). Connect the cable shield to SHIELD(39) unless it is grounded at the system controller. The mA-to-position scaling is configurable using the SPC Service Tool.

Position Monitor Output

 Connect a shielded twisted-pair cable from a (4 to 20) mA meter readout to MONITOR OUT+(40) and MONITOR OUT–(41). Connect the cable shield to SHIELD(42) unless it is grounded at the meter readout. A 4 mA signal occurs when the actuator is positioned at 0 %, and a 20 mA signal occurs when the actuator is positioned at 100 %.

Redundant SPC Interface 

These terminals are reserved for a possible future feature and must be left unconnected. DeviceNet Interface The SPC can be alternatively controlled via a network interface. The standard DeviceNet 5-pin plug-in connector allows connection to a DeviceNet network. Red/green indicators are provided to indicate the module and network status. The SPC conforms to DeviceNet Specification Release 2.0 as a Group II only slave. This product has been self-tested by Woodward and found to comply with ODVA Protocol Conformance Test Version 16.

The DeviceNet baud rate 

MAC address can be configured using the “DeviceNet” tab under the Configuration File Editor in the Service Tool. The different values are either 4 or 2 bytes long. The entire value must be gathered before the application can be updated. After each index is received, the index sent must be increased by one with looping back to zero when the max is reached. See Appendix B for specific signal addresses. Power Input Connect an (18 to 32) V (dc) power source to POWER INPUT+(54) and POWER INPUT–(55). RS-232 Port The serial port connector (9-pin Sub-D socket) is used for connecting to a PC via an extension cable (straight-through). The wiring must meet the requirements of EIA RS-232. This standard requires a maximum cable length of 16 m (50 feet) with a total capacitance of less than 2500 pF.
