[back-panel-pcb] - relay requires driver
From the specification 4.2.6, see lower, it is not clear that the reset signal needs to drive the 0.65W coil. Nor is it wanted, so best to provide a BJT/MOSFET driver.
4.2.6 The BNC connector can optionally input an external signal (5V TTL, active high) that is used for power cycling the crate.
