ACL1 Optically Isolated AC Line Monitor

Overview

The ACL1 senses whether there is ac voltage in a monitored wire and sends a signal to a data logger.

Benefits and Features

  • Optically isolated to keep the electrical systems of the monitored wire and the data logger system separate

Detailed Description

The ACL1 outputs a binary dc signal in response to the presence or absence of an ac voltage on the monitored line. An output that is less than 0.8 Vdc indicates no voltage; an output that is 3.7 to 5.1 Vdc indicates an active voltage.

Specifications

Cable Length 1.52 m (5.0 ft)
Weight 0.14 kg (0.3 lb)

Compatibility

The ACL1 uses a 5 Vdc power source (typically a CR7 or 21X control port or CAO), one single-ended analog input channel, and ground. The sensor leads are connected across (in parallel with) a monitored 95 to 240 Vac device. The ACL1 includes a 5-ft wire.

  1. We do not offer any similar devices. Such a device, however, could be constructed by the user and might consist of a 20 or 30 Vac or Vdc SPST NO relay (Single Pole Single Throw Normally Open contact relay) that is operated by the line voltage being monitored. When the relay is energized (when the 20 to 30 Vac or Vdc is supplied to the relay control coil), the contacts on the relay could carry a 5 Vdc signal from the 5 V on the data logger to one of the control ports of the data logger. This signal would then indicate to the data logger that the ac voltage is present.
