3. DESCRIPTION OF EACH MODULES

IMSRM15-E6

(6) Heater break alarm function (Optional)

The heater break alarm function is used to detect the current flowing into the load (heater) by using the

current transformer (CT), thereby producing a heater break alarm when a heater break occurs.

(Refer to P. 123.)

This function can be added only to the H-TIO-A, C or D type module.(1 point/control loop)

For H-TIO-A/C/D module with voltage/current output, no heater break alarm function can be

used.

The heater break alarm can be output as summary output (OR output) from the digital output

block in the H-PCP-A/B module. For details, refer to 3.3 H-PCP Module (P. 36).

The heater break alarm can be output independently for each channel by connecting the

H-DO-A/B/D module. For details, refer to 3.9 H-DO Module (P. 70).

(7) Control function

As standard, the H-TIO module employs the brilliant PID control method which can prevent overshoot

or disturbance (excluding the H-TIO-K module). (Refer to P. 113.)

The selectable control action type differs depending on the H-TIO module type. (Refer to the table

below.)
