Operating side safety barrier - voltage signal input single/double channel security gate

Will come from the safety of single/double channel voltage signal, through the security gate to isolate single/double output current or voltage signals to the danger zone, can control of danger such as actuator (electric/gas converter), and other instruments.It is intelligent safety barrier product, with functions of on-line fault self-diagnosis, users can also be through a dedicated handheld programmer for our products in Chinese input signal type and output range of Settings.
Explosion-proof marks:
［Exia］ⅡC
Transmission accuracy:
±0.1%F.S
Channel number:
Single/double channel

The safety barrier of danger output signal:
4-20 ma dc current:
Signal types and range in order to determine, is available
The output load capacity:
4-20 ma: 0 ~ 500 Ω;0 to 10 ma: 0 ~ 1 k Ω
O (1) - 5 v: 500 k or higher Ω;0 to 10 v: 1 m or more Ω
(need higher load capacity when ordering, please)
The security gate safety input signals:
Dc voltage: 1 ~ 5 v
Input impedance: 500 k Ω or higher
Note: need to 0 ~ 5 v, 2 ~ 10 v, 0 ~ 10 v, etc. When ordering, please determine signal types, programming is available.

National anti-explosive electric products quality supervision and inspection center (CQST) explosion-proof certification parameters (between terminals 1 and 2), (4, 5) between terminals:
