Description
Single-Channel Frequency Input Safety Barrier HD-506
The Frequency safety barrier HD-506 is used for safe separation and signal transmission between potentially explosive areas (zone 0, 1, 2) and the safe zone.
The device converts Frequency pulse signals (0.1Hz–100kHz) into a standardized output signal (e.g. 4–20mA or 0–10V) around.
Thanks to galvanic isolation between input, output and supply voltage ensures maximum safety and reliability. Online error diagnosis and PC programming options, the barrier can be flexibly adapted.
Certified according to [Ex ia Ga] IIC (NEPSI), this device is ideal for applications in the Process automation, chemical, petrochemical, energy and manufacturing industries .
