시리즈 = Alpha 2 Number of Inputs = 8 Output
타입 = Relay Input
타입 = Digital Supply Voltage = 100 ??240 V ac Number of Outputs = 6 Display Included = Yes Communication Port
타입 = RS232 Programming Interface = AS-I Number of Communication Ports = 1 Mitsubishi Alpha 2. Fifteen new function blocks have been added to the instruction set, including mathematics calculations, and PWM and SMS text messaging. Providing new possibilities for analogue signal processing and automatic status reporting An enlarged backlit information display screen with 4 lines each with 12 characters, features new options such as bar graphs and moving text displays Each of the four DIN rail/panel mount base units can be expanded with a choice of one of four I/O expansion modules to give a total of up to 28 I/Os. The expansion modules available are: Four digital 24V DC inputs with two integrated 1kHz counters, 4 digital 240V AC inputs, 4 relay outputs and 4 transistor outputs As with the earlier version of the Alpha, up to eight of the inputs on the base unit of the dc powered/input types can be configured as 0 - 10V analogue inputs. The resolution on the Alpha 2 has been improved to 20 mV (9 bits) Operating temperature range has been extended from 0 to 55°C to -25 to +55 °C, with the same precision and reliability, making the unit suitable for enclosed outdoor use and refrigeration applications A second communications port enables SMS text messages to be sent to mobile phones, e-mails to PCs and faxes in addition to using remote maintenance functions via modem. The control unit can also communicate with other controllers or peripheral components Security can be ensured by three-levels of password protection to prevent unauthorised access to program and process variable data The ALPHA 2 can be programmed directly using buttons on the front panel, but for significant improvements in programming speed and ease, ALVS programming software stock no. ; 443-3864 443-3864 and cable stock no. ; 340-1939 340-1939 is recommended. (See Alpha range for cable details and also panel mounting kits) The starter kit stock no. ; 443-3820 443-3820 offers a significant cost saving to get you started
