Two types; 4ch or 8ch

Panel space requirement is reduced

Up to 8 types of parameters of each channel can be registered. This contributes to improve efficiency of production lines and products management.

Parameters covered by Memory area:

Temperature setting, various Alarm setting, PID values, Anti-reset windup (ARW), Overlap/Deadband, Setting change rate limiter, Channel use/unuse

Communication function, alarm function, and digital contact inputs are available.

Number of inputs: 4 points (MA900), 8 points (MA901)
Input type : ※See the Input Range Code for the input range.
1) Thermocouple: K, J, T, S, R, E, B, N, W5Re/W26Re, U, L, PLII
2) RTD: Pt100 or JPt100
3) DC voltage: 0 to 5V dc, 1 to 5V dc, 1-10V dc
Sampling time: 0.5 sec. (MA900), 1 sec. (MA901)
Measurement accuracy：±(0.3% of displayed value+1 digit)　※Depends on the input and the range.
Outputs
1) Relay contact output: 1a contact
2) Voltage pulse output for SSR driving: 0/12V dc
3) Current output: 0 to 20mA, 4 to 20mA dc
4) Open collector output: Sink type
Alarm outputs (Max.3 points): Temperature alarm, Heater break alarm (HBA), Control loop break alarm (LBA)
※Alarm 1: Supplied as standard, Alarms 2 and 3: Optional
※Alarm 3 on MA900 is available with individual outputs of each channel (except heat/cool type)

CT input for Heater break alarm (Max.1 point)
Communication: RS-232C / RS-422A / RS-485
External contact input (5 points): RUN/STOP switching, Memory area switching (4 points)
※For MA901, either Heater break alarm or Communication/Digital input must be specified.
