The 1747-L40C is a fixed hardware controller designed to operate on a supply voltage of 20.4 - 27.6V DC or 24V DC +/- 15%, with a line power of 120-240V AC. This fixed controller integrates a processor with 1,024 (1K) instruction capacities, a power supply, and a fixed number of I/O points within a single package. It features capacitor-backed RAM and offers optional battery backup, with memory options through EEPROM or UVPROM. The controller has a 1K instruction capacity for program memory.
For input configurations, the nominal current is 20mA at 24V DC for input 0 and 8mA at 24V DC for all other inputs. The input has an on-state voltage range of 10-30V DC and a maximum off-state voltage of 4V DC for input 0 (5V DC for all others). The maximum turn-on and turn-off times are 8 milliseconds.
The power output current is 200mA, with an output voltage range of 20.4 - 27.6V DC or 24V DC +/- 15%. The controller supports a maximum wire size of #14 AWG and provides electrical-optical isolation of 1500V AC for 1 minute.
Operating in a temperature range of 0-60°C, it must be stored at -40 to 85°C. The typical scan time is 8 milliseconds per 1K, with a program scan hold-up time of 20-700 milliseconds after power loss. The I/O configuration includes 24 (24V DC sink) inputs and 16 AC/DC relay outputs. Additionally, it supports a high-speed counter and 24V/200mA user power.
