Sensor input
Thermocouple multi inputs (“K”, “E”, “J”, “T”) and V (voltage, current inputs).
DC voltage (0 to 5V) is input with the input adaptor of DC voltage (optional unit).
DC current (0 to 20mA) is input with the input adaptor of DC current (optional unit).
Number of input points
4 channels (Input type and ON/OFF of each channel can be selected).
Input connector
SM connector (applicable to ASTM E1684-96 Standard Specification for Miniature
Thermocouple Connectors) and special drip-proof connector (used for optional sensor).
