3300/20-01-04-03-00-00  Channel Relay

Channel Relay Module is a full-height module that provides four relay outputs. Any number of channel relay modules can be placed in any slot on the right side of the Transient Data Interface Module. Alarm driver logic is programmed using AND and OR logic and can use alarm inputs (alarm and hazard status), not-OK, or a single PPL from any monitor channel or any combination of monitor channels in the rack.You can use the 3500 Rack Configuration Software to program the alarm drivers to meet the needs of your application.Each of the outputs on the 4-channel relay module can be programmed independently to perform polling logic. The 4-channel relay module used on each relay includes alarm driver logic.

Analogue signals, there are two kinds, voltage or current signals, generally the signal transmitted by the transmitter, such as pressure transmitter to detect the pressure of the water pipe, it will output an analogue signalto 20 mA or 0-10V signal to the PLC for data processing.Amp or 0-10V signal to the PLC, PLC for data processing.

Switching input module and analogue input module. The function of the switching input module is to convert various switching signals into TTL standard signals required by the CPU. Depending on the type of input power supply, they can also be DC input modules and AC input modules. The input signals are converted into TTL (5V) standard signals by opto-coupling after voltage division, current limiting and filtering.
