TTL Relay Board Aims to Simply Switching Applications

04 October 2011

The RLY-108 8-channel TTL relay board from Auric Solutions Ltd is a simple, low-cost solution to the challenge of switching high-power signals, up to 5A/250AC or 3A/30VDC, from standard TTL signals generated either by a PC I/O board, USB I/O module, or other electronic equipment.

The RLY-108 provides 8 independently-controlled SPDT (SPCO) relays, each with an LED to indicate the energised state of the relay. The board requires an external DC power supply of 7 to 32V, drawing a maximum of 2.1W with all relays energised. Various mounting options allow the RLY-108, measuring 110 x 72 mm, to be mounted directly using appropriate standoffs, or it can be mounted to a panel or DIN rail using the optional universal mounting base available at extra cost.

The RLY-108 is priced at £120 for board only, or £130 for the board plus the universal mounting base. Prices exclude VAT and shipping.

The RLY-108 is supplied by Auric Solutions Ltd, a National Instruments Certified Alliance Partner based in the UK. Visit to obtain specifications and prices, and to download the datasheet. Send email enquiries to
