snap digital input modules page 1 data sheet form 773-080826 snap digital input modules features four channels per module 4,000-volt transient isolation convenient pluggable wiring terminals channel-specific leds operating temperature: 0 to 70 c ul and ce approved accepts up to 14 awg wire factory mutual approved (part numbers ending in fm) description opto 22 snap i/o digital input modules are part of the snap pac system. optical isolation on these modules provides 4,000 volts of transient (4000 v for 1 ms) protection for sensitive control electronics from industrial field signals. digital input modules can sense either ac or dc signals. all snap digital modules have removable top-mounted connectors to provide easy access for field wiring, and all operate on 5 vdc control logic. each digital module features integral channel- specific leds for convenient troubleshooting and maintenance. each module is factory tested twice and is ul and ce approved. in addition, part numbers ending in fm are factory mutual approved. snap input modules are used to sense the on or off status for ac or dc voltages from such sources as proximity switches, push buttons, or auxiliary contacts. the snap-idc5g is ideal for detecting 48 vdc in telecom applications. the snap- idc5-ht is designed for sensors that have a high leakage current. the snap-idc5-sw and snap-idc5- sw-nc modules supply power to an external dry contact switch and sense part numbers part description snap-iac5 snap 4-channel 90?140 vac input, 5 vdc logic snap-iac5a snap 4-channel 180?280 vac input, 5 vdc logic snap-iac5ma* snap 4-channel isolated 90?140 vac/vdc input, 5 vdc logic, with manual/auto switches snap-iac5fm snap 4-channel 90?140 vac/vdc input, 5 vdc logic, factory mutual approved snap-iac5afm snap 4-channel 180?280 vac input, 5 vdc logic, factory mutual approved snap-idc5 snap 4-channel 10?32 vdc input, 5 vdc logic snap-idc5d snap 4-channel 2.5?28 vdc input, 5 vdc logic snap-idc5fast snap 4-channel high-speed 2.5?16 vdc input, vdc logic snap-idc5-fast-a* snap 4-channel high-speed 18?32 vdc input, 5 vdc logic snap-idc5g* snap 4-channel 35?75 vac/dc input, 5 vdc logic snap-idc5af snap 4-channel high-speed 75?140 vdc input, 5 vdc logic snap-idc5gf snap 4-channel high-speed 35?75 vdc input, 5 vdc logic snap-idc5ht snap 4-channel 15?32 vdc leakage-tolerant input, 5 vdc logic snap-idc5ma snap 4-channel isolated high-speed 10?32 vac/vdc input, 5 vdc logic, with manual/auto switches snap-idc5-sw* snap 4-channel switch status input, normally open snap-idc5-sw-nc* snap 4-channel switch status input, normally closed snap-idc5fm snap 4-channel 10?32 vdc input, 5 vdc logic, factory mutual approved snap-idc5dfm snap 4-channel 2.5?28 vdc input, 5 vdc logic snap-retn4 snap 4-module retention rail (oem) snap-retn4b snap 4-module ret ention rail, 25-pack (oem) snap-retn6 snap 6-module retention rail (oem) snap-retn6b snap 6-module ret ention rail, 25-pack (oem) SNAP-FUSE4AB snap 4-amp fuse, 25-pac * ul approval pending snap digital input modules
