2、 Overview

1. Suitable for intrinsically safe proximity switches (DIN19234 NAMUR proximity switches compliant with standards) or contact switches installed in explosive areas. Through isolation, it is transmitted to the control system or other instruments in the safe area through relay contacts (or transistors, level signals) output.

2Input line fault detection function(Optional).

3For switch isolation safety barriers with input line fault detection functionWhen a line fault is detected, the line fault indicator LED on the instrument panel lights up in red.

(Note: When using the line detection function, if a mechanical contact switch is required as an input device, a line fault sensor must be connected to the input circuit to avoid the switch isolation safety barrier mistaking the normal on/off of the mechanical contact switch for an open or short circuit fault in the input circuit.)

4When selecting switch isolation safety barriers without line fault detection functionThere is no line fault indicator light on the dashboard.

3、 Technical specifications

● Power supply

Power supply voltage range: 20~30VDC

Rated supply voltage: 24V DC

Current consumption (24VDC power supply, relay output):<40 mA

● Input (intrinsic safety)

Contact switch or NAMUR proximity switch in accordance with DIN 19234.

Open circuit voltage: 8V ± 0.5V

Switch threshold: 1.2~2.1mA

Hysteresis: 0.2mA (typical value)

When there is a line fault, the open circuit current is less than 0.1mA; the short circuit current is greater than 4mA

Note: 1. When using the input line detection function, use a contact switch

When used as an input device, the connection method is as followsbelowThe picture.

2 . The two resistance values in the line fault sensor can be used by the user

Choose according to actual application needs, please specify when placing an order.

● Input/output characteristic description (in-phase control)

The factory setting state of the instrument is that the input and output are in phase, that is, the input switch is closed and the output is

The relay also engages (if it is a transistor output, the transistor is conductive; if it is a level signal, the transistor is conductive)

The output is a high-level signal. The output status indicator light on the dashboard is on.

● Line fault detection

The factory setting of this instrument is: when an input line fault is detected, the fault on the instrument panel will be displayed

The detection indicator light is on, and the output relay contact is in a released state (if it is a transistor output,

Then the transistor does not conduct; If it is a level signal output, the output is a low-level signal.

● Instrument indicator light

LFD is the input line fault indicator light (the light is on when a line fault occurs)

OUT1 is the first output status indicator light (the light is on when the relay contact is engaged)

OUT2 is the second output status indicator light (the light is on when the relay contact is engaged)

POWER is the power indicator light (when the light is on, it indicates that the instrument is powered on)

(Note: If an instrument without fault detection function is selected, there will be no LFD indicator light.). )
