Critical alarms should be visible where action happens, not only on a PC screen. This wireless remote alarm module adds physical output capability to the HD35 system, allowing alarm events from connected data loggers to activate external signaling devices or actuators.
Two bistable relays with potential-free contacts can be associated with alarm conditions through the HD35AP-S software. The module works with all HD35AP base unit versions and uses wireless RF communication, with 868 MHz, 902-928 MHz or 915.9-929.7 MHz versions depending on the model.
On-site status is easy to check. LEDs indicate alarm presence, battery charge and RF communication status, while the PING button helps verify whether the base unit can be reached. The internal Li-SOCl2 battery supports typical operation for 1 year, depending on how often alarm conditions are generated.
Two bistable relays with potential-free contacts are available for association with alarm conditions in HD35AP-S software.
The module connects to the HD35 wireless network and communicates with the base unit via RF transmission.
A front push-button connects or disconnects the device from the wireless network and supports the PING function for RF checks.
The internal buzzer sounds cyclically during alarm conditions, with beep patterns indicating relay 1, relay 2 or both relays active.
Power is supplied by an internal Li-SOCl2 not rechargeable battery, with typical battery life of 1 year depending on alarm frequency.
The ABS housing is designed for wall mount installation, with optional flanges for fixed installation.
