Weather Resistant Surge Protector for RS485 Control & 12VDC Power Lines
SP-RS485-12V-O
Ideal for applications such as video surveillance cameras and access control.
Protects sensors running on 22 AWG 2-wire sensor cables or 12VDC power lines against the effects of electrostatic discharge, faulty wiring and lightning.
RS485 protection
Stage 1 clamping voltage: ±90V
Stage 2 resistance: 3.3 Ohms
Stage 3 clamping voltage: ±7.5V
12VDC power lines protection
Stage 1 clamping voltage: ±90V
Stage 2 current rating: 3A
Stage 3: 12V TVS (transient voltage suppression) diode
Screw terminal pairs for RS485 and 12VDC power lines protection.
If a contact sensor comes with a 12VDC AC adapter, the power lines can be wired to the power terminals for protection.
Will also protect two single ended data, analog or control lines.
Impact and weather resistant enclosure with locking hinged cover.
