The USB-RLY16L is a low power version of the USB-RLY16 relay module board (60-5062). The module board, containing 8x relays, is powered and controlled entirely via standard USB bus and the 8x volt free contact relay outputs have a current rating of up to 16A each. The relays are of the Single Pole Changeover (SPCO) type and, unlike the other relay module boards in the series, are latching types - meaning that the relays will retain their contact position in the absence of power. LED indication is provided via a red LED mounted adjacent to each relay to indicate whether it is a position 1 state (LED On) or position 0 state (LED off). |
