2.0 Description
The A753 has one 4-20mA input and two discrete inputs. Other analog inputs are
available always refer the label on the side of the unit to determine proper input. Dis-
crete inputs can be either wet or dry. The status of the discrete inputs is displayed on
the front panel as A1 and A2. The 4-20mA input signal is replicated on the receiver’s
4-20mA output. Similarly the state of switches A1 and A2 are mapped to the receiver’s
A1 and A2 respectively. To facilitate installation, the transmitter is designed for 35mm
DIN mount and powered by the industry st24Vdc (11 to 32 Vdc). The receiver
model A750 is sold separately. The Model 753 can be used with a repeater (Model
A759). If a repeater is used – please refer to section 4.4 for configuration.
