The DI732 combines two fully independent isolator channels in one housing. The inputs feature separate 19Vdc/22mA auxiliary supplies to drive 3-wire or loop powered field transmitters.

All inputs and outputs are coding plug configurable for the most common process signals. Factory default is 4-20mA. Final calibration can be trimmed by using the front accessible SPAN (S) and ZERO (Z) potentiometers. The optional alarm point on channel 2 is also set by potentiometer utilising the adjacent test socket.

The DI732 can be used in a number of ways:

• Two channel isolation and any mix of signals.
• Isolation of two 4-20mA field transmitters
• Signal splitting (one input and two isolated outputs).

The wide swing DC/DC converter allows for two power supply ranges: 10-60Vdc (16-42Vac), 80-280Vac (80-300Vdc). Isolation is 2kVr.m.s. between all 6 ports. Connections are done via unpluggable screw type 8-way terminals.
