3. DESCRIPTION OF EACH MODULES

IMSRM15-E6

(3) Alarm function

One H-TIO module is provided with two alarm points (Alarm 1 and Alarm 2) as standard.

Alarm 1/2 types are those selected by the H-PCP module.

Alarm type:

Deviation high alarm Process high alarm

Deviation low alarm Process low alarm

Deviation high and low alarm Process high alarm with hold action

Band alarm Process low alarm with hold action

Deviation high alarm with hold action Deviation high alarm with re-hold action

Deviation low alarm with hold action Deviation low alarm with re-hold action

Deviation high and low alarm with hold action Deviation high and low alarm with re-hold action

(4) Alarm output function (Optional)

An alarm can be output from the H-TIO module itself (only for the H-TIO-A/E/H/R types).

Number of output points: 1 point (relay contact output)

Output type : Select any of temperature alarm output (ALM1), temperature alarm output (ALM2),

heater break alarm output (HBA)

or loop break alarm output (LBA)

(The output type needs to be specified in the model code at the time of ordering.)

Only H-TIO-A can be selected.

Only H-TIO-A, H-TIO-E or H-TIO-R can be selected.

Each 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 respective alarm (Alarm 1/2) 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).

For H-TIO-A/E/H/R type modules, an alarm can be output from each module (optional).

(5) Loop break alarm function (Excluding H-TIO-H/J type modules)

The loop break alarm function is used to detect a load (heater) break, a failure occurring in any

external operating device (magnet relay, etc.) or a failure occurring in the control system (control

loop) caused by an input (sensor) break. (Refer to P. 124.)

The loop 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 loop 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).
