The general specifications of the CQM1-TC20j/TC30j conform to those of the
CQM1H/CQM1 Series.
Units for thermocouples
(CQM1-TC20j)
K, J, T, L, R, S, B
2 loops or 4 loops (2-loop model has heater burnout alarm)
NPN or PNP output with short-circuit protection
Power supply voltage: 24 VDC
Maximum switching capacity: 100 mA per output
Leakage current: 0.1 mA max.
Residual voltage: 0.8 V max.
ON/OFF control, advanced PID control (2 degrees of freedom), or manual
operation
°C Ranges
(Process value ±0.3% or ±1 °C,
whichever is larger) ±1 digit max.
°F Ranges
(Process value ±0.3% or ±2 °F,
whichever is larger) ±1 digit max. (See
note 1.)
The accuracy is given when the cold
junction compensator on the terminal
block is used. Always use the cold
junction compensator on the terminal
block. (See note 2.)
