The module (Item No. 750-1689) has two independently switchable relay outputs (RO1 ... RO2) and is particularly suitable for applications that, e.g., individually electrically isolated Outputs are required, high loads must be switched or controlled with different voltage types (e.g., DC and AC voltage). The module supports operating voltages up to 250 VAC and 250 VDC.<br/>The electrically isolated outputs can be freely combined with each other, so that Cat. 2 or Cat. 4 architectures up to SIL3 or PLe are possible. Details on possible wiring variants can be found in the product manual.<br/>The relay outputs must be controlled via safe digital outputs (e.g., the outputs of the 75x-667/000-004, 750-1665/000-004 module), in which case an unsafe enable of the relay outputs must also be provided via the process image.<br/>The status of the safe relay outputs and the temperature for each relay are detected and transmitted to the controller via the non-safe process image, where they must be evaluated as diagnostics.<br/>The field and system levels are electrically isolated from each other.<br/>The individual safe modules can be arranged in any configuration in the fieldbus node.<br/>The module (Item No. 750-1689) was evaluated by UL in accordance with UL/CSA 61010-1, UL/CSA 61010-2-201 and UL 121201, CSA-C22.2 No. 213. The functional safety assessment according to the above standards was carried out by TÜV Rheinland.
