Solid-state re­lays boost chan­nel ca­pac­ity in space-con­strained ap­pli­ca­tions

DEMM Engineering & Manufacturing - - PRODUCT WATCH -

RS Com­po­nents (RS) now of­fers a new own-brand range of highly minia­turised solid-state re­lays (SSRs), which en­able small pan­els or cab­i­nets to sup­port ex­tremely high chan­nel count.

The SSRs have the in­dus­try’s low­est pro­file of just 71mm, mak­ing them ideal for ap­pli­ca­tions that re­quire iso­la­tion be­tween a PLC and field wiring but are sub­ject to se­vere en­clo­sure-height con­straints, says RS. Their 6.2mm foot­print is shared with other minia­ture me­chan­i­cal re­lays, which helps en­hance f lex­i­bil­ity and sim­pli­fies panel de­sign chal­lenges.

Adding to their phys­i­cal size ad­van­tages, the re­lay hous­ings pro­vide space for iden­ti­fi­ca­tion la­bels of up to 24 char­ac­ters. Clear ter­mi­nal mark­ings also help en­sure ac­cu­rate in­stal­la­tion and main­te­nance. Screw or push-in ter­mi­na­tion op­tions give f lex­i­bil­ity for de­sign­ers to meet the needs of dif­fer­ent mar­kets world­wide. In ad­di­tion, all mod­els fea­ture an in­te­grated test socket.

The new SSRs com­bine the su­pe­rior re­li­a­bil­ity of solid-state tech­nol­ogy with press-fit in­ter­nal con­struc­tion that fur­ther en­hances ro­bust­ness. They are pack­aged in f lame-re­tar­dant hous­ings that meet UL 94-V0 and the NFF I2/F2 trans­porta­tion stan­dard, spec­i­fied over the in­dus­trial tem­per­a­ture range -40°C to 85°C, and carry CE, UL, CSA and GL ap­provals.
