Chapter 8. Appendices
8.1 Appendix A: Relay box pin-outs
When Network Trigger is used with Güralp's SCADA Relay Control Box, part number CMG-STA-RLY0, detected events can trigger the operation of four independent relays.
8.1.1 Output connections
The output connections are located on the bottom face of the relay box. The pin-outs are described in the following section. Mating connectors are provided with the unit to allow you to connect your own equipment.
The two “Alarm” plugs provide access to four pairs of normally open relays. The two “Analogue” sockets are not used by the Network Trigger application.
8.1.2 Alarm (relay) outputs 1/2 and 3/4
These are standard 4-pin “mil-spec” plugs, conforming to MIL-DTL-26482 (formerly MIL-C-26482). A typical part-number is 02E-08-04P although the initial “02E” varies with manufacturer. Suitable mating connectors are provided and have part-numbers like ***-08-04S. They are also available from Amphenol, ITT Cannon and other manufacturers. |
