heater burnout alarm Externally supplied power supply voltage: 24 VDC +10%/-15%
output Maximum switching capacity: 100 mA (per output)
Leakage current: 0.3 mA max.
Residual voltage: 3 V max.
Temperature control ON/OFF control or PID control with two degrees of freedom (Set with pin 6 on the Unit's DIP
method switch.)
Control operation Forward or reverse operation (Set with pins 4 and 5 on the Unit's DIP switch.)
RUN/STOP control Supported (Controlled from the CPU Unit through bits allocated in the Special I/O Unit area.)
Operation with CPU The Temperature Control Unit can be set to continue operating or stop operating when the CPU
Unit in PROGRAM Unit is in PROGRAM mode. (Set with pin 1 on the Unit's DIP switch.)

PID constant
Indication accuracy Centigrade: ±0.3% PV or ±1°C (whichever is
larger) ± 1 digit max.
Farenheit: ±0.3% PV or ±2°F (whichever is
larger) ± 1 digit max.
• The accuracy will be ±2°C ± 1 digit max. when
using an L-type thermocouple or using a K or
T-type thermocouple below −100°C.
• The accuracy will be ±3°C ± 1 digit max. when
using an R or S-type thermocouple below
200°C.
• The B-type thermocouples may not be accu-
rate below 400°C. (See note 2.)
