4.5.4.Hi-Current Relay Outputs

Three form C relay outputs are provided on the rear panel on the nine pin connector (See Figure 4-5). The relays are labeled “Relay 1,” “Relay 2,” and “Relay 3.”

The relays are dry contact type form C (SPDT) relays with Normally Open (N.O.), Normally Closed (N.C.) and Common (COM) contacts. The relays are capable of driving loads of up to 250VAC, 5A. For maximum contact life, the relays should only be used to drive resistive loads. Contact life may be dramatically shortened if inductive loads are driven without any provision for minimizing high voltage “inductive kick” that can occur. See Section 7.2.6 to configure the concentration for the alarm trigger.

4.5.5.Digital Serial Interfaces

There is one external communications port available on the M465M that can be configured as RS232, RS485 (Half Duplex,) or Ethernet (10Mbit.) This section provides only a brief overview of the digital serial connections, for more detailed information on configuring and using the digital serial interfaces, see Section 8.

4.5.5.1. RS232 Connection

With the instrument configured for RS232, connection can be made to the DB-9 connector, labeled “RS232/485”, or to the three “COM” pins on the “General I/O” connector. See Section 8.2 for additional details.

When using RS232, a 9-pin serial cable (TAPI P/N WR77) can be used to connect the instrument to a standard PC (personal computer) serial port.
