The 1760-L12NWN Pico Expansion I/O Module is an AC expansion I/O module by Allen-Bradley with 8 digital inputs and 4 relay outputs, which provides expanded I/O capability for the Allen-Bradley Pico Controllers. The module has 8 Digital inputs with 24V AC control, and OFF and ON state voltage ranges of 0 to 6V AC and 14 to 26.4V AC at 50/60Hz, respectively. It has an input current of 2mA at 24V AC, with a signal delay time of 66.66ms for the ON state at 60Hz, and of 16.66ms for the OFF state at 60Hz, and it also has two 0 to 10V DC Analog inputs. The 1760-L12NWN has 4 Relay outputs with 250V AC operational voltage, in a single group, which cannot be connected in parallel, and the Relay output is protected by a B16 circuit breaker or by an 8A slow blow fuse. It provides 300V AC voltage isolation between power supply and inputs, 300V AC between the Coil and Contact, and between 2 contacts, by using reinforced insulation, and it has a Relay contact with an 8A Conventional Thermal current. The relay output has a load rating of >500mA at 12V AC, and it provides short-circuit resistance via the B16 circuit breaker with a 900A maximum short-circuit rating and a rated impulse voltage withstand of 6000V. Its relay output has a filament lamp load of 1000W at 230/240V AC, with Relay operating frequencies of 10Hz for mechanical switching, of 2Hz for a resistive lamp load, and of 0.5Hz for an inductive load. The 1760-L12NWN has a functional temperature range of -25 to 55 ºC (-13 to 131 ºF) at a non-condensing relative humidity limits of 5 to 95%, and a storage range of -40 to 70 ºC (-40 to 158 ºF). It comes in an IP20 rated enclosure and is built to withstand 15G operational shock for 11ms and 2G vibration at 57 to 150Hz.
