Product description
Switching input isolation type safety barrier, receiving switch or
proximity switch inputs from hazardous areas, and transmitting
them to a safe place for output through safety barrier isolation,
with relay output normally open/normally closed conversion
setting function. This product requires independent power supply
and isolation of the power supply, input, and output terminals.

DRG-���� � in � out
【Power supply voltage】: ��～��VDC
【Signal input characteristics】:
On site sensor side power supply voltage: approximately �V (when
open circuit)
When the on-site input current is>�.�mA, it indicates "ON"
When the on-site input current is less than �.�mA, it indicates "OFF"
Switch hysteresis effect: ���us
【Relay output characteristics】: Response time: ��ms
Drive capacity: ���VAC/�A, ��VDC/�A
【Input fault detection function (K� and � are set to ON)】:
When the input is disconnected or short circuited, the output relay
is disconnected and the red indicator light is on.
【Switch setting function】:

No line fault detection function
Note: For switch input (�), K� and K� need to be set to the OFF state,
and there is no line fault (disconnection, short circuit) detection
function; If there is a need for line fault (wire breakage, short circuit)
detection function, a ��K ٠resistor should be connected in parallel
at both ends of the switch, and a ��� ٠resistor should be connected
in series, as shown in switch (II). K� and K� should be set to the ON
state.

Safety and explosion-proof certification
The isolation type safety barrier and the on-site intrinsic safety
instrument are connected to form an intrinsic safety explosion-proof
circuit (intrinsic safety circuit). The system must confirm before use:
�. The explosion-proof level of on-site intrinsically safe instruments
should comply with the operating environment, and they should be
certified by a nationally authorized explosion-proof product
certification agency and have obtained an explosion-proof
qualification certificate.
�. The certification parameters between the isolated safety barrier
and the on-site intrinsic safety instrument are clear and comply with
GB/T����.��, ���.�, etc.
�. If there are unclear parameters, it is necessary to form an intrinsically
safe circuit system and obtain explosion-proof products
authorized by the state confirmation from the certification body.
