HA88B01KNX Universal module 8 inputs / 4+4 outputs

Type: eelectron HA88B01KNX Universal module 8 inputs / 4+4 outputs

Bus System: KNX

Degree of protection: IP20

Mounting: DIN rail

GTIN: 8054144521176

The HA88B01KNX device is an EIB / KNX module with 4 triac outputs at 24... 230 V AC for controlling thermoelectric valves and with 4 relays 16A-230VAC; the devices also contain 8 inputs for dry contacts (potential-free). The 4 triac outputs can be configured as:
• 4 channels for valve control in ON / OFF or PWM mode
• 2 channels for 3-point valve control
The 4 relay outputs can be configured as:
• 4 outputs for light/load control
• 4 channels for valve in PWM (electromagnetic drives)
• 2 channels for controlling blinds
• 2 channels for 3-point valve control
• Groups 2,3,4 relays for special functions using logic blocking.

The device is suitable for controlling 2/4 tube fan coils up to 3 speeds; outputs not used by the application can be used to control other devices. The inputs can be connected to buttons or switches (potential-free) and can be used for on/off commands, dimming, blinds or blinds/scenarios, sequences, step commands, etc. Inputs 1 to 4 can be configured as outputs to activate individual signaling LEDs (see electronic LED code LD00A01ACC / LD00A11ACC) or they can be configured as analog inputs for connecting NTC temperature probes (see electronic probes code TS00A01ACC / TS00B01ACC ), with which the possible to send 4 temperature measurements to the bus or 4 thermostat modules.

Each thermostat module controls 2 stages with an integrated PI controller to control heating and cooling devices, valves, 2 and 4 pipe fan coils, etc. There are 3 more thermostat modules available in the device, a total of 4. available to implement simple expressions with logical or threshold operators or complex expressions with algebraic and conditional operators; It is possible to use predefined algorithms such as proportional temperature and humidity control or dew point calculation.

Outputs 1,2,3,4 must all be connected to 24V AC or 230V AC;
it is not possible to connect both voltages or in any case 2 different voltages!
• Output 1 must be used first, outputs 2,3,4 cannot be used if output 1 is not connected.
