10.2 Technical data, CU240E-2 Control Unit
Feature Data
Operating voltage Supply from the Power Module or an external 24 V DC supply (20.4 V … 28.8 V, 0.5 A) via
control terminals 31 and 32
Heat loss 5.0 W plus power loss of output voltages
Output voltages 18 V to 30 V (max. 200 mA)
10 V ±0.5 V (max. 10 mA)
Setpoint resolution 0.01 Hz
Digital inputs
• 6 digital inputs, DI 0 … DI 5, isolated;
• Low < 5 V, high > 11 V, maximum input voltage 30 V, current consumption 5.5 mA
• Response time: 10 ms without debounce time (p0724)
Pulse input Digital input 3, maximum pulse frequency 32 kHz
Analog inputs (differential
inputs, resolution 12 bits)
AI 0, AI 1: 12-bit resolution, differential inputs, 0 V … 10 V, 0 mA … 20 mA and -10 V … +10 V,
reaction time: 13 ms ± 1 ms
Can be configured as additional digital inputs: Low < 1.6 V, High > 4.0 V.
Reaction time: 13 ms ± 1 ms without debounce time (p0724).
Digital outputs / relay
outputs
• DO 0: Relay output, 30 V DC / max. 0.5 A with resistive load
• DO 1: Transistor output, 30 V DC / max. 0.5 A with resistive load, protection against
incorrect voltage polarity
• DO 2: Relay output, 30 V DC / max. 0.5 A with resistive load
Update time of all DO: 2 ms
For applications, which require UL certification, the voltage at DO 0 and at DO 2 must not
exceed 30 V DC referred to ground potential and must be supplied via a grounded class 2
power supply.
Analog outputs AO 0, AO 1: 0 V … 10 V or 0 mA … 20 mA, reference potential: "GND", resolution 16 bit,
update time: 4 ms
Temperature sensor
• PTC: Short-circuit monitoring 22 Ω, switching threshold 1650 Ω
• KTY84
• ThermoClick sensor with dry contact
Fail-safe digital input
(Basic Safety)
• DI4 and DI5 form a fail-safe digital input
• Maximum input voltage 30 V, 5.5 mA
• Response time:
– Typical: 5 ms + debounce time p9651 (6 ms, if p9651 = 0)
– Worst-case scenario: 15 ms + debounce time p9651 (16 ms, if p9651 = 0)
You will find the "Extended Safety" data in the Safety Integrated Function Manual, see section
