Description
The TU837V1 MTU can have up to 8 I/O channels. The maximum rated voltage is 250 V and maximum rated current is 3 A per channel. The MTU distributes the ModuleBus to the I/O module and to the next MTU. It also generates the correct address to the I/O module by shifting the outgoing position signals to the next MTU. The MTU can be mounted on a standard DIN rail. It has a mechanical latch that locks the MTU to the DIN rail. The latch can be released with a screwdriver. Two mechanical keys are used to configure the MTU for different types of I/O modules. This is only a mechanical configuration and it does not affect the functionality of the MTU or the I/O module. Each key has six positions, which gives a total number of 36 different configurations. Features and benefits • Up to 8 individually isolated channels of field signals and process power connections. • Each channel has two terminals and one is fused. • Allows a mix of isolated and grouped channels. • Process voltage return can be connected to two individually isolated groups. • Connections to ModuleBus and I/O modules. • Mechanical keying prevents insertion of the wrong I/O module. • Latching device to DIN rail for grounding. • DIN rail mounting.
