Therefore, field wiring connects directly through the terminal block rather than through a separate signal termination assembly.\u003c\/p\u003e\n\u003cp\u003eThe unit supports a maximum 50 V voltage level and limits each I\/O channel to 2 A. In addition, the process connection supports a maximum current of 5 A. These limits define the electrical loading conditions for connected field circuits.\u003c\/p\u003e\n\u003cp\u003eThe supplied data identifies the TU845 as a redundant termination unit. However, the data does not specify a backplane communication protocol, communication velocity, firmware dependency, or I\/O module compatibility matrix. These parameters should therefore be verified against the associated ABB I\/O system documentation before installation.\u003c\/p\u003e\n\u003cp\u003eThe specified 500 V AC dielectric test voltage provides the stated insulation test level between applicable electrical sections.
