Safety Controller Combines Two or More Relays

The SC10 Series safety controller from Banner Engineering monitors safety devices on smaller machines with hazardous motion. The controller, with its 10 inputs, including four that can be converted to output, can replace two or more safety relay modules. It features automatic terminal optimization (ATO), which makes it possible to increase the number of inputs from 10 to 14 to accommodate more input devices. Two independent 6-amp relay outputs with three normally open sets of contacts let users create independent safety zones with different outputs for different safety functions. The controller can be configured using Banner’s free safety controller software and a PC. The software provides an icon-based, drag-and-drop user interface that generates ladder logic and wiring diagrams to clearly identify terminal assignments. Configurations can be tested before being used to reduce the risk of error. Confirmed configurations can be saved to an SC-XM3 external drive and loaded onto additional SC10 safety controllers using the controller S micro USB port. Ethernet IP, Profinet, Modbus, and PCCC provide two-way communication between the SC10 and other devices. The safety controller can send up to 256 status updates to a PLC or HMI for troubleshooting. It can also receive up to 80 non-safety inputs, including manual reset, On/Off commands, enable mute functions, and cancel Off-delay. The device can monitor a wide range of input devices, providing safe stop and start functions. They are typically used to monitor E-Stop buttons, rope pulls, safety light curtains, scanners, safety switches, and other safety devices.
