Model EM-T-7A Extension Module One- or two-channel control for use with a Primary Safety Device Features Extension Module provides additional safety outputs for a Primary Safety Device (for example, an E-stop Safety Module or a 2-hand control module), if controlled and monitored by this device Features four 6-amp switching channels for connection to control-reliable machine power interrupt circuits Four redundant output channels Contact status outputs are provided for connection to the Primary Safety Devices monitoring input 24V dc operation Housed in a narrow, 22.5 mm (0.9 ) DIN-rail-mountable module Convenient plug-in terminal blocks Design complies with standards UL 991 and EN 60204 Description R R C The model EM-T-7A 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 EM-T-7A 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 (K1 and K2 in Figure 3). The outputs of the Extension Module follow the action of the safety outputs from the Primary Safety Device which control it, within a switching delay time of approximately 20 milliseconds. The Extension Modules four outputs are each rated for up to 250V ac/dc at up to 6A. 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 (see Figure 3). This monitoring circuit prevents the Primary Safety Device from being reset if contacts of either K1 or K2 of the Extension Module fail in a shorted condition. The Extension Module has indicators for input power (green), and status of internal relays (K1 and K2, both green) (see Figure 1). There are no adjustments and no user- serviceable parts. See page 6 for information regarding repair service. This Extension Module is not a point-of-operation guarding device, as defined by OSHA WARNING . regulations. It is necessary to install point-of-operation guarding devices, such as safety light curtains and/or hard guards, to protect personnel from hazardous machinery. Failure to install point-of-operation guards on hazardous machinery could lead to serious injury or death. Printed in USA P/N 54208B0BExtension Module Model EM-T-7A IMPORTANT NOTICE .
