PID CONTROLLER FOR KS 800 BUS
Eight independent control loops can work in different configurations. Apart from universal measurement inputs, KS 800 also has configurable logic inputs and a number of configurable logic outputs (option with continuous outputs). The controller does not have a display and operator panel - configuration and monitoring via a service link on a PC computer with BlueControl software or through communication links - to choose from RS422 with the ISO1745 protocol, Profibus-DP, Device-Net, CANopen. It is also possible to connect the KS 800 controller to the P-Open system or the BT800 operator terminal (up to five regulators per one panel - the required CANopen connection).
Basic technical data of KS800:
- eight independent control loops (signaling, positioning, DPID control continuous, two- and three-position (with cooling algorithm), step, cascade - all with self-tuning function and start-up option (initial heating with reduced power)
- universal, configurable measurement input: L, J, K, N, S, R type thermocouple (measurement error = 2K), Pt100 (measurement error = 2K), resistance input 0 ... 400 ohms, voltage input -100mV. ..100mV (measurement error = 0.1%) with state monitoring (open circuit, polarity)
- analogue input for monitoring current drawn by 0 ... 42mA AC actuators (with break or overload monitoring)
- six optoisolated logic inputs 24VDC - configurable functions, four inputs can be configured as control loop outputs
- fifteen (plus four additional configured inputs) logic outputs 18 ... 30VDC, max. current 70mA, short-circuit proof - configurable functions (including controller outputs, alarms, threshold crossing, etc.)
- optionally eight continuous outputs 0/4 ... 20mA or 0 ... 10V
- LED diodes signaling the operating status and status of outputs
- 3 configurable alarm outputs
- housing: IP20, mounted on a 35mm DIN rail
- working temperature from 0 to + 60C, humidity = 75%
- 8 channel regulator with universal optoisolated measuring inputs,
- most types of regulators available, including cascade and step controller, and heating-cooling control
- power 24VDC 5W
- use in plastic processing machines
- available versions with analogue control outputs
- heating current measurement for each control loop
- work auto / manual
- 4 configurable control inputs / outputs
- RS422 / 485 communication, CAN / CAN open, ProfiBus-DP
- the controller can be configured using a utility program or BT 800
- possible expansion of the control system with additional KS 800 modules or other automation modules (eg discrete I / O modules)
- the ability to connect to SS800-based ready power systems based on SSRs
