Monitoring Analogue Input Card – IA2001
Analogue Input Card – IA2001 is a Safety related 4-20mA analog input with 16 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.
