The Three Channel Input/Output Module provides three voltage-free, single pole, change/over relay outputs and three monitored switch inputs.
Full Details
Electrical Description

The Three Channel Input/Output Module is loop powered and operates at 17–28V DC with protocol voltage pulses of 5–9V.

Operation

The Three Channel Input/Output Module supervises one or more normally-open switches on each of the three inputs. It is set to return an analogue value of four in the event of an open or short-circuit fault and 16 during normal operation. The status of the inputs is reported by three input bits. The change-over contacts of each relay are operated by three command bits. Ten LEDs, six red and four yellow, are fitted to the PCB. All LEDs except the isolator LED can be disabled to conserve loop current. The LEDs are disabled using the eighth segment of the DIL switch. For each channel, one red LED is illuminated to indicate that the relay is set; a second red LED is illuminated to indicate that the switch input is closed and a yellow LED is illuminated to indicate an open or short-circuit fault. A separate yellow LED is illuminated whenever the built-in isolator has sensed a short-circuit loop fault. It is recommended that the LEDs are disabled for normal operation.

Mechanical Construction

Dimensions and weight: 250 x 175 x 75mm 621g (in enclosure) 140 x 160 x 18mm 111g (PCB only)

Backward Compatibility

The module will operate only with control equipment using Apollo XP95 or Discovery protocol. It may also be used to replace earlier Series 90 Three Channel Input/Output Units.
