Figure 2-25 Connection of interface relay 230 V 6DR2804-8B
The interface relay 230 V, 4 relays (6DR2804-8A) contains 4 relays. Terminals 8/1 to 8/9 must
then be connected accordingly in addition to the terminals 7/1 to 7/8.
Attention: Observe the max. switching voltage! (excessive increases in resonance in phase
shift motors, see chapter 1.4.2, page 13)

2.2.3 Alternative connection for I- and U-input
D 0/4 to 20 mA signals
The 49.9 Ω input impedance is connected across the input signals AE+ and AE- (AE1 to
AE3 in the standard controller and in module 6DR2800-8A by means of jumper settings and
by external wiring on the option module for AE4 and AE5).
If the signal is still required during service work in which the terminal is disconnected, the
input 49.9 Ω input impedance 0.1 % must be connected to the terminal between AE+ and
AE--. The internal 49.9 Ω resistance must then be disconnected by appropriate jumper
settings or by rewiring.
