Inputs
Universal inputs models for
thermocouple (J, K, T, E, R or S under ITS-90), 0-55mV, RTD under
DIN 43760, 4-20mA, 1-5Vdc and 0-10Vdc selected by user. Input
impedance of 250 ohms for mA, 10 M ohms for 5Vdc and 2 M ohms
above 5Vdc.
Frequency inputs models for signals up to 30kHz, from 300mVpp to
30Vpp and 70Vdc max. DIN 19234 compliance for intrinsically safe
NAMUR sensors.
Note: Universal or frequency inputs require different instruments.
See order code.
Outputs
4-20mA (750 ohms maximum load),
1-5Vdc or 0-10Vdc analog retransmitter.
Up to two optional modules galvanically isolated to 300Vac from power supply and inputs.
Up to four SPST and SPDT relays rated for 3A at 220Vac.
Logic signal, open collector transistor, 40mA/24Vdc maximum with
isolation.
Note: There are 4 fitting connectors internally, so, the total
number of optional output modules is 4.
See order code.
Serial
Communication
RS-232 or RS-422/485 with 50Vdc
isolation.
