The Allen-Bradley 1756-L7SP is a crucial component of the GuardLogix controller family, designed as a partner for the primary GuardLogix Safety controller, compatible with models such as 1756-L71S and 1756-L73SK. It features a current draw of 5 mA at 1.2 VDC and 800 mA at 5.1 VDC, with power and thermal dissipation rates of 2.5 W and 8.5 BTU/hr, respectively, while offering 30V isolation voltage for safety. Operating within a temperature range of 0 to 60 °C, this controller fits into any available slot in the 1756 chassis, aligning beside the primary controller to form a 1oo2 architecture suitable for Safety Integrity Level 3 applications.
