A. Each CIM motor and Fisher-Price motor must be connected to one and only one approved speed controller. These motors must not be connected to relay modules.
D. Each other electrical load (motor or actuator) must be supplied by one and only one approved speed controller, or one and only one relay module.
Only CIMs and FPs have to have a speed controller. All other motors (i.e. RS-395) can be controlled by a relay.
<R39> All active PD Board branch circuits shall be protected from overload with an appropriate value auto resetting Snap Action circuit breaker (from the KOP or identical equivalent).
B. Each relay module branch circuit must be protected with one and only one 20-amp circuit breaker on the PD Board. No other electrical load can be connected to the breaker supplying this circuit.
This does say that each relay must have a 20A breaker on the
PD, but nothing about on the relay itself.
