3.924Vdc Isolated Output (Option)

The Isolated 24Vdc Output is an option that provides 24 Volts DC @ 100 milliamps to power external (current loop) sensors. The output is isolated to 1000 volts from all internal voltages and ground. The output is also protected against short circuit.

The output is polarized and is marked for positive (+) and negative (-). This option is field installable.

3.10 Isolated Serial Interface (Option)

A standard DB9 Female connector is required for the RS232 to connect to an IBM PC compatible computer using a null modem cable. The RS232 interface can support cable runs up to 50 feet [16 m]. The RS485 connection is via two wire (twisted pair) cable (a DB9 Female adapter connector is required) and can support cable runs up to 4000 feet [1300 m].

The RS232 and RS485 connections are mutually exclusive and are selected using pin 1 of the DB9 connector – see right.

The interface is isolated from internal circuitry to 500 volts. The RS485 requires a 120 ohm terminating resistor if it is the last unit on the drop. All Serial Interface connections are made through the DB9 female connector. An adapter connector is included that brings out the RS485 connections to a set of screw terminals and has the terminating resistor on the board. The RS485 connection is marked A and B for duplex 2 wire connection. A is + and B is -.

If the terminating resistor is required it is necessary to open the adapter shell and insert the jumper to enable the termination.

The connections to the DB9 female connector are as follows:
