GE | TGT-AI0V-8-0-BC | ANALOG MODULE

Product Description：

The D20 Analog module is composed of two detachable modules, WESTERM D20 A and WESDAC D20 A. The bottom module, WESTERM D20 A, is where all field wirings are terminated. The top module, WESDAC D20 A, processes the data acquired and communicates this to the main D20 processor, see Figure 2. The WESTERM D20 A is the termination module for the WESDAC D20 A analog input module. All field, I/O, and power terminations for the WESDAC D20 A are made on the WESTERM D20 A. Up to 32 analog inputs can be accommodated on compression type terminations.

Through the use of input adapter modules, individual inputs can be configured for voltage or current. Voltage ranges currently accepted are 1, 5 or 10 volt full scale unipolar or bipolar. Current inputs are sampled via a shunt resistor and therefore almost any common current range can be accepted. A wetting source is supplied for current loop inputs. Capacitors and varistors are equipped to provide Surge Withstand Capability (SWC) as well as impulse protection on all field inputs. Loop voltage for field transducers can be provided on an individual input basis. The voltage source can be either the input to the WESDAC D20 A or an external source.
