Product Description

Product feature:
Quite frequently there is a demand to monitor two load cells, and a possible circuit, safe in IIC, is shown. Here, the lower voltage drop of the MTL7766Pac is an advantage. The MTL7766Pac supplies power to the bridge(s) while two MTL7761Pac barriers interface with the sense and pick-off circuits.

Specification:

Number of channels

Two

Location of switch

Zone 0, IIC, T6 hazardous area

Div.1, Group A, hazardous location

Location of proximity detector

Zone 0, IIC, T4-6 hazardous area, if suitably certified

Div.1, Group A, hazardous location

Hazardous-area inputs FSM

FUNCTIONAL SAFETY MANAGEMENT IEC 61508:2010 Inputs conforming to BS EN60947-5-6:2001 standards for proximity detectors (NAMUR)

Voltage applied to sensor

7 to 9V dc from 1k ±10%

Input/output characteristics

Normal phase

Outputs closed if input > 2.1mA (<2k in input circuit)

Outputs open if input < 1.2mA (> 10k in input circuit)

Hysteresis: 200µA (650) nominal

Line fault detection (LFD) (when selected)

User selectable by switches on the side of the module.

Line faults are indicated by the LED for each channel.

Line fault relay is energised and channel output relay de-energised if input line-fault detected Open-circuit alarm
on if I in < 50µA Open-circuit alarm off if I in > 250µA Short-circuit alarm on if Rin < 100 Short-circuit alarm off if Rin >
360 Note: Resistors must be fitted when using the LFD facility with a contact input 500 to 1k in series with switch 20k to
25k in parallel with switch
