The IDA4 Set point Controller is a 85-250VAC or 12 to 40VDC powered four (4) set point digital controller with a 5 digit Blue OLED display which is supplied in a din rail mount enclosure that can switch 240VAC at five (5) amperes resistive with 99% dead band.
The instruments functions are touch switch programmable from the front panel. A 24VDC loop power supply at 30mA is available for the direct connection of two (2) wire transmitters. Screw terminal electrical connection is included.
Accepts all standard process signals
85-250VAC 47-63 Hz supply or factory fitted 24VDC isolated supply
Low cost - High performance
Screw terminal electrical connection
Four set point relays with form C contacts
High contrast 5 digit Blue OLED display of 10 mm digit height
Din rail mount enclosure
24VDC loop supply for 2 wire transmitters
Digital instrument with eeprom storage of programmed variables and touch switch programming of input range, output on and off point, high, low or control operation and decimal point position
The instrument has a bipolar differential input. To realise the accuracy a temperature compensated band gap reference is used in the ratio metric measurement system. The standard instrument is set for 4-20mA and 0-10VDC operation. Other ranges of are available. Please consult the factory.
Four switch point relays are provided with form C (changeover) contacts rated at five (5) amperes 240VAC resistive.
Each output can be configured as active high, active low with hysteresis or control alarm [output configured to be active between high and low set points].
The IDA4 has a 4.5 digit 10mm character height high contrast light emitting diode (LED) display with a viewing distance of 3 metres with programmable intensity.
The decimal point position is programmed from the front panel.
0-70 degrees Celsius
0-90% rh non-condensing
Instrument Power Supply
120/240VAC 47-63 Hz or factory fitted DC to DC converter from 12 to 40VDC.
Transducer Power Supply
A 24VDC at 30mA transducer power supply.
Din rail mounting enclosure 100 mm wide by 75 mm high by 110 mm deep.
Configuration of the Instrument
This is a digital instrument and the display intensity, decimal points, input range, relays on and off switch points and hysteresis are programmed by the front touch buttons and the values are stored in eeprom for 10 years.
