Scame Sistemi Brand 8 Channels-Analog Input Device Control Card Model S81 – F4003

Description

A Safety related 4-20mA analog input with eight (8) inputs, each having two threshold settings.

The following transducer types can be connected: Explosive Sensors,

Toxicity Sensors, Oxygen Sensors, Temperature Sensors, General 4-20mA sensors.

The channel is tested during operation every 30 seconds.

The card is equipped with a 4-20mA Output that supplies the current value measured at the Input.

The analog value can be transferred to a DCS using a RTU Modbus module, part number S81-F7006-1.

in case of discrepancy between the set signal and the read signal, the unit promptly warns about the failure condition.

The Output is tested for the following: line opening, short circuit towards positive pole, short circuit towards negative pole,

failure of piloting DMOS device, over-temperature of piloting DMOS device, power voltage outside the limits allowed.

To increase output current, channels can be connected in parallel.
