EM-T-7A

The EM-T-7A is a 2-pole DIN-rail mount Extension Module provides additional forced-guided (positive-guided) relay contacts for a Primary Safety Device, such as an E-stop safety module or a two-hand-control module. Controlled by the safety outputs of the primary safety device, the extension module provides four redundant outputs. These outputs may be connected to control-reliable machine power interrupt circuits. Each of the four extension module outputs is a series connection of two forced-guided relay contacts. The outputs of the extension module follow the action of the safety outputs from the primary safety device which controls it, within a switching delay time of approximately 20 milliseconds. The extension module offers an output circuit at terminals Y1 and Y2 which provides K1 and K2 contact status information for connection to the monitoring input of the primary safety device. The extension module has indicators for input power (green) and status of internal relays.

• Convenient plug-in terminal blocks
• Design complies with standards UL 991 and EN 60204
